A 2" spacer will reduce fork travel by 2" (lower the front 2"). Fork oil? I use Automatic transmission fluid on lowered street/strip bikes, heaver fluid will only slow the valving. You ALWAYS spring the bike for rider weight. The shim stack or oil weight wont help. I would only trim 1.50"-1.75" off the factory spacer  :wink:

Did mine today, good  writeup. If you heat up  the threaded joins on the damper tube & valve assembly with a hot air / heat gun they undo alot easier (factory use loctie). Just becareful of the damper seal. Make sure the inner hole in your new spacer is big enough to sit on the flat edge of the valve assembly, not jam on the taper where the threaded section is. Leigh

These are good words of advice from Lee re. tapering the spacer and heating up the threaded spots. I did my forks on the weekend and even a heat with the wifes hairdryer was enough to soften the loctite to make it easier getting the threads loose. Definitely suggest making the spring compressor as well. I added a retainer to both ends on the spring compressor for safety sake. No blood spilt

Thanks again Corey and Lee  :thumb:

P.S I took 1.5" off the factory spacer and the my fork travel has dropped by roughly 2.5" (Although I haven't put the oil in yet as I am waiting for some new seals). I did not measure my new spacers beforre I put them in but I assume they are the 2" that I asked for.

I'll be doing this asap. What is the best amount to cut off if you want forks to not expand to run with out a strap. If I use a 2" spacer for example what needs to be taken off the factory piece?

The only problem i had the bottom allen would not come out had to
go threw the top of the forks to get them apart.But went back together
with no problem.
